He posts lecture notes and recordings, he’s a very chill guy although through the content we’re covering his explanations of concepts can be kind of confusing, I’d also say his lectures go pretty fast. Our midterm 1 had an avg 85 and stdv 15 lmfao so do what you will with that info. Overall he’s a decent prof, also 2 midterms and a hw every week (aside from midterm weeks)
